I'm considering creating a classroom blog this year. I can only hope it will work with my school's security system . Here are some questions on which I would really appreciate your input: What are the best free sites? How much time does it take to set it up/update? Do I need a special program to create/update the blog (i.e., old-time web site creation software, etc.) What should be on it? How often should it be updated? How do I set it up so parents can get email or smartphone notifications?
